2. Description of Related Art

Throughout human history, pets have provided their owners with enormous amounts of companionship, loyalty, and entertainment, making it obvious why, to this day, pet animals remain popular. Most pet owners consider their pet animal as a part of the family. As such, most pet owners treat their pet with the same affection and protective care as they would with family members. It is this bond that makes most pet owners take meticulous care of their pets, often with the guidance of a veterinarian, to keep their pet healthy and maintaining a high quality of life. Achieving this goal with pets including dogs, cats, birds and mice, results in an everlasting battle with the common enemy of warm-blooded vertebrates: The ectoparasite, of which the main species is more commonly known as the flea.

Fleas are insects adapted with mouthparts able to pierce skin and suck blood from mammals and birds. That is, they are external parasites living by hematophagy (feeding on the blood of a host animal). There are numerous flea species; most often identified by the species of their primary host, such as, cat fleas (Ctenocephalides felis) whose preferred host is the domestic cat. However, in spite of their given name, flea species will feed off a wide spectrum of hosts. Thus, many flea species are possible threats to a variety of pets at any given time. It is with this constant threat in mind that pet owners must pay particular attention to their pets to prevent any possible flea infestation and/or to rid their pet quickly of an existing flea infestation.

With the advances of science and technology, chemical treatments are now the preferred method for eradicating fleas. Several commercial products are available for killing fleas on dogs and cats. Most of these products are chemicals that pet owners apply to the pet's skin. The products kill fleas and prevent a re-infestation for about days. The chemicals used include imidacloprid, fipronil, selamectin, permethrin, and metaflumizone. Most of these chemicals have been widely utilized in the United Sates, Europe, and Asia. When utilized according to the manufacturer's recommendations, these products have been very effective at killing fleas. In fact, in the United States, pet owners spend over $1 billion annually for flea and tick control products. Nonetheless, reports are increasing about fleas developing resistance to the chemical effects of these compounds. For example, annual surveys of small-animal veterinarians have shown the percentage of United States veterinarians who have seen flea resistance to the chemicals nearly doubling in the past few years.

Veterinarians are in a unique position since pet owners with flea problems are most likely to seek professional advice and solutions from their veterinarian. Therefore, a veterinarian reporting increased resistance is a clear sign that popular professional products are becoming less effective. Currently, manufacturers of flea control products routinely test flea susceptibility to their chemicals in highly controlled laboratory tests with a single species of flea, Ctenocephalides felis. However, there are over 2,000 known species of fleas, and chemical manufacturers cannot adequately monitor resistance among that many species. Accordingly, veterinarians do not have a device for testing flea susceptibility to the products they provide their pet owner clients. Instead, they dispense professional products to pet owners that have been effective in the past. Unless pet owners call to complain that a recommended product does not kill fleas, veterinarians have no way of determining flea resistance to the product.

This raises the need for a convenient device that veterinarians can utilize in their clinics to test the effectiveness of different products before dispensing them to pet owners. Such a device needs to be able to capture fleas for each patient the veterinarian observes because there are so many different species. Susceptibility to different products may vary across the 2,000 species of fleas, so each of the fleas infecting each patient should be tested as a unique case.

Flea combs, consisting of closely spaced metal or plastic tines, have long been utilized to comb pets and thereby dislodge fleas. However, flea combs are susceptible to clogging from pet hair. Once fleas are dislodged, they are not easily captured for testing. Several patented devices have attempted to overcome this flaw through teaching mechanical removal of fleas from dogs and cats, which rely on first capturing the pest, but then almost immediately killing them through drowning, suffocating, poisoning or electrocuting means (since fleas are highly resistant to physical harm). These devices leave an operator with no opportunity to observe a live flea's reaction to commercial flea control products, and therefore such devices and methods are not particularly suitable as research tools.

Another device teaches a pet grooming device with a detachable head. The head piece is designed as a typical comb, with a pattern of bristles and openings designed to brush hair through a stroking motion. The headpiece is attached to a handheld vacuum apparatus, wherein a stream of air generated by the vacuum motor can be utilized to pull fleas from an animal's hair during the brush stroke of the grooming process. As fleas get caught in the air stream, they forcibly enter into a windowed vacuum bag housed within a transparent second chamber. Windowed sections of the vacuum bag allow a user to observe the inner contents of the bag. Once the grooming process is complete, the disposable vacuum bag containing any captured fleas can be removed from the device and sealed off by a drawstring before being discarded. Other than observing that the fleas have been captured, there is no means of analysis of flea behavior.

The windowed sections in the aforementioned device are supposed to provide a view of any of the captured contents within the vacuum bag. However, since fleas are small (typically between 1.5 to 3.3 mm long) they will be hard to find, either live or dead, within the bag, looking through just the windowed section alone. Further, observing live fleas in this device has the added difficulty of dealing with their extreme agility. Moreover, it will be difficult to discern between a flea and a spec of detritus captured by the vacuuming action. Also, this device does not allow a user to conveniently place chemical products within the bag to see their affect on the captured fleas, and instead a user may only observe fleas dying through suffocating means.

Additionally, there are numerous other grooming devices for pets that capture fleas from an animal during the grooming process that utilize a vacuum generated stream of air to provide the sucking force necessary to separate the flea from the animal's hair. However, once caught in the air stream the fleas are killed in a variety of ways. For example, one device teaches a staggered maze of fly-paper covered walls that are placed directly within the path of the air stream to catch fleas as they flow past. Another device places an electric grid within the path of the air stream to electrocute fleas as they flow past. Still another device utilizes a chamber filled with a mixture of water and chemicals, placed at the end destination of the air stream, so that fleas will be forcibly blown into the liquid where they will eventually be poisoned and/or drowned. Lastly, there are devices that direct fleas caught in the air stream into an enclosed containment chamber, wherein they are killed through various methods of chemical poisoning. While all of these devices have the express intent of mechanically removing fleas with a vacuum device and killing them by various exposures, none of them are provides for testing and observing live flea resistance to different chemicals utilized in commercial products.

Therefore, it is readily apparent that there is a need for a portable and easy to use apparatus that can mechanically collect live ectoparasites so they may be researched and observed while being exposed to various chemical products.

BRIEF SUMMARY OF THE INVENTION

Briefly described, the preferred embodiment overcomes the above-mentioned disadvantages and meets the recognized need for such an apparatus by providing an ectoparasite diagnostic apparatus comprising a vacuum motor, a microscope, a display connected to the microscope that is observable from outside the apparatus, a non-flexible pivoting door and a containment chamber. The apparatus is utilized by removing live ectoparasites from a subject animal, disposing the live ectoparasites in the containment chamber, treating the live ectoparasites with a flea control compound and observing the effect of the flea control compound on the live ectoparasite via the display.

The preferred embodiment is unique in that it can be utilized outside of a research laboratory setting to test the resistance of any species of fleas extracted from, for exemplary purposes only, a dog or a cat. The apparatus may utilize a standard flea comb to dislodge fleas and make them visible in a pet's hair coat. When fleas are dislodged, the vacuum motor draws the live fleas into the containment chamber.

In one embodiment, the apparatus consists of, for exemplary purposes only, a hand-held, 12-volt battery-powered vacuum suction assembly, with two attachments. One attachment is a tapered, tubular housing section with an elongated orifice that intensifies the vacuum suction. The other attachment is a transparent containment chamber where live fleas are deposited. The containment chamber comprises a non-flexible pivoting door that seals fleas in the containment chamber. The containment chamber is easily detachable from the vacuum assembly and tubular attachment. When a sufficient number of fleas have been captured for testing, the operator can quickly attach another containment chamber to capture another sample of fleas. This allows the operator to capture multiple flea samples from a pet for testing with different chemicals.

Additionally, many dogs and cats are easily disturbed by loud noises such as a vacuum motor, which makes it difficult to utilize vacuum assemblies near pets. In one embodiment, loud noises are minimized by utilizing a trigger for short bursts of suction power. The operator only activates the vacuum motor when they see live fleas during the combing process. Thus, the apparatus will most likely be utilized in a veterinary clinic where an assistant can work with the operator to ensure that the pet remains calm during the combing.

In another embodiment, a method for testing different chemicals is accomplished by introducing fibrous pads that have been treated with one of the common chemicals in commercial flea control products. The fibrous pads are treated with an amount of insecticide that resembles the amount of exposure fleas will get from, for exemplary purposes only, a dog or cat treated with the same insecticide. The small pads can be introduced into the containment chamber by opening the non-flexible pivoting door and inserting the pad into the containment chamber. Since the containment chamber is transparent, the operator and/or pet owners can easily observe the effects of exposure on the captured fleas. By testing different insecticides, the veterinarian and pet owner can pick the most effective product for quickly killing fleas, and avoid utilizing any products that have less efficiency.

According to its major aspects and broadly stated, the preferred embodiment is an apparatus for observing live ectoparasites comprising a containment chamber and an electronic imaging member. The electronic imaging member comprises a magnifying device and the magnifying device comprises a microscope having a digital display. The containment chamber is dimensioned to dispose live ectoparasites in the field of the microscope and further comprises a non-flexible pivoting door and a wire screen. The non-flexible pivoting door is controlled by an external knob and provides entrance and exit of the live ectoparasites into the containment chamber. The wire screen permits travel of moving air with the live ectoparasites therethrough, while also retaining the live ectoparasites within the containment chamber. The containment chamber further comprises a receiving aperture. The receiving aperture receives either a flea comb or a tubular housing with a nozzle.

In an alternate embodiment, the apparatus for observing live ectoparasites further comprises a hand-held vacuum assembly. The hand-held vacuum assembly comprises a vacuum motor in a housing with a manipulatable switch, and an opening that permits attachment of the containment chamber. The vacuum assembly removes the live ectoparasites from a subject animal and deposits the live ectoparasites within the containment chamber. A wire screen is disposed at an end of the containment chamber that is attached to the vacuum assembly. The wire screen prevents fleas from being sucked into the vacuum motor. The vacuum assembly further comprises a non-flexible pivot door at the other end of the containment chamber. The non-flexible pivot door is opened during vacuuming and closed after fleas are captured, so that live ectoparasties can be retained safely within the confines of the containment chamber in a live state. The live ectoparasites may subsequently be exposed to a fibrous pad treated with a popular veterinary flea control chemical to determine resistance of the live ectoparasites to the popular veterinary flea control chemical.

Additionally, the preferred embodiment is a method of capturing live ectoparasites for observation comprising the steps of obtaining an apparatus having a digital microscope with display and a containment chamber comprising a non-flexible pivoting door, removing live ectoparasites from a subject animal, disposing the live ectoparasites in the containment chamber, closing the non-flexible pivoting door and observing the live ectoparasites in the containment chamber via the digital microscope with display.

The method further comprises the steps of optionally vacuuming the live ectoparasites from the subject animal into the containment chamber, or optionally utilizing a flea comb to remove the live ectoparasites from the subject animal and disposing the flea comb in a receiving aperture in the containment chamber, such that the flea comb is disposed within the field of observation of the digital microscope, treating the live ectoparasites with a flea control compound and observing the effect of the flea control compound on the live ectoparasites.

Lastly, the preferred embodiment comprises a live flea observation apparatus having a containment chamber, a digital microscope with display and a vacuum assemble, such that the display is observable without the live flea observation apparatus. The live flea observation apparatus further comprises a non-flexible pivoting closure door and an aperture for receiving a flea comb.

More specifically, the preferred embodiment is a ectoparasite diagnostic apparatus comprising housing, a vacuum switch and a containment chamber. The housing comprises a handle, a back foot, a front foot, a secondary handle and a power cord, wherein the handle comprises an end. The housing further comprises a microscope, a mesh screen, a vacuum motor and a display, wherein the microscope is in electrical communication with the display. The end of the handle comprises the microscope, which is positioned to view fleas within the containment chamber. Additionally, the handle allows a user to grip the ectoparasite diagnostic apparatus as a hand-held apparatus, and the power cord supplies power to the ectoparasite diagnostic apparatus. When the ectoparsite diagnostic apparatus is not utilized, the power cord is wrapped around the secondary handle, and the ectoparsite diagnostic apparatus is supported on a surface via the front and back feet.

In the preferred embodiment, the containment chamber comprises a top, a bottom, a non-flexible pivoting door and a knob. The non-flexible pivoting door is disposed on top of the containment chamber. The mesh screen is disposed on the bottom of the containment chamber. The non-flexible pivoting door pivots open and close via the knob. The containment chamber also comprises a receiving aperture, which is dimensioned to receive a flea comb. The flea comb combs a subject animal to dislodge fleas and is then inserted into the receiving aperture. Fleas are then suctioned into the containment chamber by pushing the vacuum switch, thereby activating the vacuum motor. Once the vacuum motor is activated, fleas are pulled into the containment chamber against the mesh screen, while still allowing air and other debris to filter past the mesh screen. The non-flexible pivoting door is closed and the live fleas are confined in the containment chamber.

In another preferred embodiment, the containment chamber comprises a top, a bottom, a non-flexible pivoting door and a knob. The non-flexible pivoting door is disposed on top of the containment chamber. The mesh screen is disposed on the bottom of the containment chamber. The non-flexible pivoting door pivots open and close via the knob. The vacuum motor is activated via a vacuum switch. Once activated, the vacuum motor pulls fleas into the containment chamber against the mesh screen. The non-flexible pivoting door may be closed, such that the live fleas are confined in the containment chamber. The containment chamber further comprises a receiving aperture to receive a tube having a nozzle. The nozzle contacts a subject animal for fleas and the fleas are then suctioned into the containment chamber by the vacuum motor, thereby pulling the fleas into the containment chamber against the mesh screen. It will be recognized by those skilled in the art that the containment chamber and the non-flexible pivoting door may comprise a translucent material, such as rigid plastic or glass, thereby allowing an operator to visually determine if fleas have been suctioned into the containment chamber, and if the non-flexible pivoting door should be closed to confine fleas within the containment chamber.

In an alternate embodiment, the ectoparasite diagnostic apparatus comprises a vacuum assembly, a containment chamber and a nozzle. The vacuum assembly is secured to the containment chamber, and the containment chamber is secured to the nozzle. The vacuum assembly comprises a vacuum motor, a rechargeable battery door, a gripping handle and a trigger. The vacuum motor is activated by the trigger, which activates electric power to the vacuum motor, thereby creating suction at the nozzle.

The non-flexible pivoting door is on top of the containment chamber, and the mesh screen is on the bottom of the containment chamber.

The alternate embodiment is utilized by a user gripping the handle of the ectoparasite diagnostic apparatus. The user's index finger is then positioned on the trigger. The other hand of the user combs a subject animal with a flea comb. During combing, fleas are dislodged and brought to the surface of the hair coat of the subject animal. When fleas appear on the surface of the coat, the user moves the nozzle of the ectoparasite diagnostic apparatus to the surface of the hair coat and activates the vacuum motor by pulling the trigger, thereby suctioning fleas through the nozzle and into the containment chamber. The user then closes the non-flexible pivoting door via the knob, thereby concealing fleas in the containment chamber. When one or more fleas are concealed, the user detaches the containment chamber from the vacuum assembly and the nozzle. Subsequently, the user may selectively insert a small fibrous pad pre-treated with a veterinary flea control chemical, and observe if the fleas succumb to the chemical.

The preferred embodiment is utilized by a user combing a subject animal with a flea comb. During combing, fleas are dislodged and brought to the surface of the hair coat of the subject animal. When fleas appear on the surface of the coat, the user inserts the flea comb into the receiving aperture. The vacuum switch activates the vacuum motor, thereby suctioning fleas caught in the flea comb into the containment chamber against the mesh screen. The user then closes the non-flexible pivoting door via the knob, thereby concealing fleas in the containment chamber. When one or more fleas are concealed, the user selectively inserts a small fibrous pad pre-treated with a flea control chemical into the containment chamber. The microscope observes if the fleas succumb to the chemical and shows flea interaction with the flea control chemical on the display. The display rotates on a hinge, thereby allowing a user to perpendicularly rotate the display away from the ectoparasite diagnostic apparatus.

Additionally, preferred embodiment is utilized by a user by placing a tube with a nozzle into the receiving aperture. The nozzle is then placed on a subject animal. The vacuum switch activates the vacuum motor, thereby suctioning fleas through the nozzle and into the containment chamber against the mesh screen, thereby entrapping fleas in the containment chamber. When one or more fleas are within the chamber, the user opens the non-flexible pivoting door via the knob, and selectively inserts a small fibrous pad pre-treated with a flea control chemical into the containment chamber. The microscope observes if the fleas succumb to the chemical and shows flea interaction with the flea control chemical on the display.

Accordingly, a feature and advantage of the present invention is its ability to capture fleas from infested dogs or cats for testing resistance to chemicals intended to eradicate such pests.
